Why does AdMob get charged?

Question

Google Ads

A month ago I decided to try to add ads from google - AdMob to the ios application. Everything was not bad, a penny slowly came ($ 1-3 per day). Since it was new, sometimes I checked it several times a day, everything is ok. But starting from the new month, some strangeness has gone, you look conditionally in the morning shows an estimated income of $ 1.5, in the afternoon you refresh the page already conditionally $ 0.30, then a few dollars will accumulate and write off again during the next checks. Yesterday, for example, at 23.50 it showed $ 7 for today, and today it shows (already for yesterday) that it is only $ 1.29. This was not exactly the case last month. What could it be or is it normal? I don’t watch ads myself, and even more so I don’t click, I don’t buy traffic - everything is from search.

And I also looked at the details for the month in the Payments section: -38$. I don’t understand why there are so many write-offs due to “Invalid traffic”, I found topics on the forums, but there were write-offs by a few percent, I get 45%.

Who works with admob, tell me if all this is normal? What can be done? There are suggestions that now little by little they are deducted from the daily income for the last month for some kind of "Invalid traffic", maybe this is so? The truth is why so many.
